TruthBear Maritime Chokepoint Region Gauge
x402
TruthBear Maritime Chokepoint Region Gauge is a paid API for AI agents from api.truthbear.co, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-14).
Runs a 4-leg sequential chain assessing current passage conditions at a named maritime chokepoint, aggregating sea state thresholds, anchorage congestion, vessel wait counts, and realized daily transit counts from IMF PortWatch.

How this service works
[4-LEG] Maritime chokepoint passage chain, one chokepoint (?loc=hormuz, suez, panama, malacca and more): leading sea state against operating thresholds -> current anchorage congestion, vessels waiting -> realized daily transits from IMF PortWatch (confirmation gate). A chain, not one reading: confidence = how many legs are lit, in order. Sources: IMF PortWatch, NOAA, Open-Meteo. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.25 per call.
Output
A JSON object with up to four sequential chain legs: (1) leading sea state vs operating thresholds, (2) current anchorage congestion level, (3) vessel wait count, and (4) realized daily transit count confirmed by IMF PortWatch. A confidence score indicates how many legs are lit in order. Descriptive only — no forecasts or advice. Returns HTTP 422 with no_charge if data is unavailable.
Example use cases
Suez Canal shipping disruption alert
“Check the Suez Canal chokepoint right now — is it congested, how many vessels are anchored and waiting, and are daily transits running at normal levels?”
Malacca Strait supply chain monitoring
“I need a full status on the Malacca Strait chokepoint today — sea state against thresholds, current anchorage congestion, and confirmed daily transit numbers from PortWatch.”
Panama Canal capacity assessment
“What does the current passage chain look like at the Panama Canal? I want to know sea conditions, how many ships are queued, and the realized transit count.”
Technical details
Endpoint
GEThttps://api.truthbear.co/gauge/chokepoint-regionWhen to prefer
Use this endpoint when you need a multi-signal, sequentially confirmed picture of maritime chokepoint conditions — not just raw vessel counts or a single metric, but a chained assessment that cross-validates sea state, congestion, and realized transit throughput. Prefer it over generic AIS feeds or single-source vessel trackers when you need a confidence-weighted summary grounded in IMF PortWatch confirmation as the final gate.
Side effects
- 422 no_charge returned when any required data source (IMF PortWatch, NOAA, Open-Meteo) is unavailable — caller is not billed
- Invalid or unsupported loc parameter value returns an error
- Partial chain confidence if only some legs return data (e.g. sea state available but transit data missing)
- Network timeout if upstream data providers are slow or unresponsive
